Description

Technical Field

[0001] This utility model relates to the technical field of hot-melt equipment, and in particular to an automatic hot-melt mechanism. Background Technology

[0002] A hot melt machine is a device that uses electric heating to transfer heat to the welding surfaces of components to be joined. It uses a heating plate to melt the contact surfaces of the connected components and then rapidly press them together, thus solidifying the upper and lower components into a single unit. The core structure of a hot melt machine typically includes an upper template, a lower template, and a heated template, and is equipped with a pneumatic or manual control system. It is generally suitable for welding and drilling components made of thermoplastic materials, thin-walled metal sheets, etc.

[0003] Core components of radiators, such as fins and base tubes, are mostly made of metal materials, such as aluminum, copper, or alloys, and require high-precision machining to ensure heat dissipation efficiency and structural strength. Hot-melt drilling machines are used in radiator manufacturing to process thin-walled metal sheets, forming precise holes by melting the material at high temperatures, avoiding deformation or burrs. They are suitable for applications such as air conditioner radiators and automotive radiators. Compared to traditional mechanical drilling, hot-melt technology can improve processing efficiency by 30%-50% and reduce material waste.

[0004] Based on this, Chinese patent document CN117124602A discloses a hot melt machine, which includes a base plate, a drive adjustment mechanism fixedly connected to the top of the base plate, a clamping mechanism fixedly connected to the top of the drive adjustment mechanism, and a processing mechanism fixedly connected to one end of the top of the base plate. The clamping mechanism includes a top circular plate, which is fixedly connected to the top of the drive assembly. A mounting base is fixedly connected to the top of the top circular plate. Rectangular sliders are slidably connected to both sides of the mounting base. T-shaped pieces are slidably connected inside the rectangular sliders. A vertical block is fixedly connected to one end of the T-shaped piece. A positioning shaft is fixedly connected to the bottom right side of the vertical block. A rectangular positioning strip is fixedly connected to the side of the mounting base. There are two T-shaped pieces, and a third spring is fixedly connected between the two T-shaped pieces. This hot melt machine, through the designed drive adjustment mechanism, facilitates the hot melt processing of multiple workpieces, thereby ensuring stable operation when the top circular plate moves and providing a certain degree of support for the hot melt operation of the workpieces.

[0005] However, the aforementioned hot melt machines still have technical problems with insufficient safety protection. Specifically, under normal operating conditions, the surface temperature of the core components of the hot melt machines disclosed in the prior art typically reaches 200-300°C. Contact with high-temperature surfaces or molten materials during operation may lead to severe burns or even skin carbonization. If operators are not wearing protective gloves or goggles, molten adhesive splashes can directly injure the operator's eyes or exposed skin. Therefore, a systematic set of protective measures can be implemented to reduce the overall accident rate of hot melt machine operations. Utility Model Content

[0009] Furthermore, the feed drive cylinder is mounted on the support frame, and the feed drive cylinder is drivenly connected to the telescopic piston rod.

[0010] Furthermore, the drive connection portion connects the telescopic piston rod and the reciprocating platform, respectively.

[0011] Furthermore, the guide frame has a guide sleeve and a guide rod.

[0012] Furthermore, the two guide sleeves are disposed opposite to each other on both sides of the drive connection portion, and each guide sleeve is disposed in the reciprocating frame.

[0013] Furthermore, the two guide rods are respectively arranged opposite to each other on both sides of the telescopic piston rod, each guide rod is inserted into the guide sleeve, and each guide rod is respectively connected to the support frame and the bottom of the housing.

Therefore, this utility model, an automatic hot-melting mechanism, solves the technical problem of how to improve the safety performance of hot-melting machines during operation.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0025] Please refer to the following: Figures 1 to 2 This utility model discloses an automatic hot-melt mechanism comprising: a housing 1, a limiting fixture 2, a support frame 3, a feed drive mechanism 4, a reciprocating platform 5, a guide frame 6, a hot-melt head 7, and a safety light curtain 8; the limiting fixture 2 is disposed at the bottom of the housing 1, the support frame 3 is disposed within the housing 1, the feed drive mechanism 4 is disposed on the support frame 3, and the reciprocating platform 5 is disposed below the feed drive mechanism 4 relative to the limiting fixture 2; the guide frame 6 is connected to the bottom of the housing 1 and the support frame 3 respectively, the reciprocating platform 5 is movably connected to the guide frame 6, the feed drive mechanism 4 is drivenly connected to the reciprocating platform 5, and the hot-melt head 7 is disposed below the reciprocating platform 5; the safety light curtain 8 is disposed on one side of the housing 1.

[0026] Specifically, when the automatic hot-melt mechanism of this utility model is in operation, the workpiece to be hot-melted can be placed in the limiting fixture 2, and the limiting fixture 2 limits the placement of the workpiece; the feed drive mechanism 4 starts and drives the reciprocating table 5 to descend along the limit of the guide frame 6, thereby driving the hot-melt head 7 to descend until the hot-melt head 7 completes the hot-melt process on the workpiece placed in the limiting fixture 2. Then, the feed drive mechanism 4 drives the reciprocating table 5 to rise and reset along the limit of the guide frame 6, thereby resetting the hot-melt head 7. During the aforementioned hot-melt process, the transmitter of the safety light curtain 8 continuously emits densely arranged infrared beams at the opening on one side of the housing 1, forming a "light curtain" or "light curtain" covering a specific area. Its receiver continuously monitors the beam status through a photosensitive element array. When a person or object enters the light curtain area and blocks the beam, the corresponding photosensitive sensor at the receiver interrupts signal reception, converting the light signal into an electrical signal. The signal is filtered, amplified, and then transmitted to the safety controller, triggering preset safety mechanisms such as emergency stop and alarm. This system has an extremely short response time, typically ≤20ms. Therefore, the equipment can be quickly stopped by cutting off the power source, preventing operators from accidentally putting their hands into the working area during the hot-melt process, thus avoiding safety accidents. Therefore, this utility model's automatic hot-melt mechanism solves the technical problem of how to improve the safety protection performance of a hot-melt machine during operation.

[0027] Furthermore, the feed drive mechanism 4 includes a feed drive cylinder 401, a telescopic piston rod 402, and a drive connection part 403; the feed drive cylinder 401 is mounted on the support frame 3, the feed drive cylinder 401 is drivenly connected to the telescopic piston rod 402, and the drive connection part 403 connects the telescopic piston rod 402 and the reciprocating table 5 respectively.

[0028] Furthermore, the guide frame 6 has a guide sleeve 601 and a guide rod 602; the two guide sleeves 601 are disposed opposite to each other on both sides of the drive connection part 403, and each guide sleeve 601 is disposed in the reciprocating platform 5; the two guide rods 602 are respectively disposed opposite to each other on both sides of the telescopic piston rod 402, each guide rod 602 passes through the guide sleeve 601, and each guide rod 602 is respectively connected to the support frame 3 and the bottom of the housing 1.

[0029] Specifically, when the feed drive cylinder 401 is activated, it can drive the telescopic piston rod 402 to extend or retract, thereby driving the reciprocating frame 5 to move downward or upward through the drive connection part 403. When the reciprocating frame 5 moves downward or upward, the guide sleeves 601 provided on both sides can reciprocate downward or upward along the limit of the guide rod 602, thereby making the movement of the reciprocating frame 5 driving the hot melt head 7 more stable and accurate.

[0030] Furthermore, the hot melt head 7 is a conventional hot melt head structure in the art, which can rapidly heat up through pulse current or electric heating element to achieve precise and controllable local heating; and transfer heat to a preset position on the workpiece to be melted.

[0031] Furthermore, the safety light curtain 8 is equipped with a signal transmitter 801 and a signal receiver 802; the signal transmitter 801 and the signal receiver 802 are arranged opposite to each other, and are respectively located on both sides of the housing 1. Specifically, the signal transmitter 801 can emit an infrared beam, and the signal receiver 802 can receive the infrared beam emitted by the signal transmitter 801, convert the optical signal into an electrical signal, and transmit it to an external control terminal, such as a computer or industrial control computer, so that the external control terminal can issue control commands such as starting or stopping the feed drive mechanism 4 and the hot melt head 7 based on the received signal.

[0032] Furthermore, a control module 9 is provided on the adjacent side of the housing 1. The control module 9 has a first control switch 901, a second control switch 902, and an emergency stop switch 903. The first control switch 901 and the second control switch 902 are disposed opposite each other on the adjacent side of the housing 1, and the emergency stop switch 903 is disposed between the first control switch 901 and the second control switch 902. Specifically, the first control switch 901, the second control switch 902, and the emergency stop switch 903 are respectively connected to the feed drive mechanism 4 and the hot melt head 7. When the operator needs to start the feed drive mechanism 4 and the hot melt head 7, the first control switch 901 and the second control switch 902 need to be pressed simultaneously. When the feed drive mechanism 4 and the hot melt head 7 complete one processing action, they will automatically stop working. Alternatively, when the user presses the emergency stop switch 903, the feed drive mechanism 4 and the hot melt head 7 will also stop working.

[0033] In summary, the automatic hot-melt mechanism of this utility model comprises a housing 1, a limiting fixture 2, a support frame 3, a feed drive mechanism 4, a reciprocating platform 5, a guide frame 6, a hot-melt head 7, and a safety light curtain 8. The limiting fixture 2 is provided at the bottom of the housing 1, the support frame 3 is provided inside the housing 1, the feed drive mechanism 4 is provided on the support frame 3, and the reciprocating platform 5 is provided below the feed drive mechanism 4 relative to the limiting fixture 2. The guide frame 6 is connected to the bottom of the housing 1 and the support frame 3, the reciprocating platform 5 is movably connected to the guide frame 6, the feed drive mechanism 4 is drivenly connected to the reciprocating platform 5, and the hot-melt head 7 is provided below the reciprocating platform 5. The safety light curtain 8 is provided on one side of the housing 1. When a human body or object enters the light curtain area formed by the safety light curtain 8 and blocks the light beam, the receiving end of the safety light curtain 8, corresponding to the photosensitive sensor, interrupts signal reception and converts the light signal into an electrical signal. The signal is then filtered, amplified, and transmitted to the safety controller, triggering preset safety mechanisms such as emergency stop and alarm. This system has an extremely short response time, typically ≤20ms; therefore, the equipment can be quickly stopped by cutting off the power source, preventing operators from accidentally putting their hands into the working area during the hot-melt process, thus avoiding safety accidents. Therefore, this utility model, an automatic hot-melt mechanism, solves the technical problem of how to improve the safety protection performance of a hot-melt machine during operation.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
